Allison Tranny choice

New Member

I have the option of buying one of a couple ambulances that I will convert to an RV Camper ... I need help/htoughts/guidance on power train options. Both have mileage in the 180,000 range and about 9,000 hrs ... One is an International 4700 chassis with a DT466 engine and an AT545 tranny ... the other is a Cummins 8.3 engine with an MD 3060 tranny.

I realize that at these miles maintenance is probably the key issue, but both look good, so let's assume the maintenace has been okay ... does one tranny have an advantage over the other in this situation. I know the AT545 is a classic "fluid drive" and the MD 3060 is electronicly controlled. I believe the AT545 is a four speed and the MD is a six speed.
